HAIRPROOF / YOUR PRIVACY

Privacy & contact

HairProof helps you explore hair products and see where the information came from. We check hair stories and updates before they appear. Don’t add your contact details to public stories or email us a private return code. To limit abuse, the application stores a daily keyed IP hash, normally for up to three days; expired counters are cleared on the next submission attempt. Hosting providers may retain technical request logs. If a response is interrupted, your submission may have been saved; do not retry automatically. Lost return codes cannot be recovered here.

Browsing and outside websites

When you browse hair products, our database provider handles those requests. Hosting and database providers may process technical information such as IP addresses and request logs. Opening an external source takes you to another website with its own privacy practices.

HairProof uses Vercel Web Analytics on public pages to measure aggregate visits, page views, and referral information. It does not use advertising trackers or record your private hair-story return code in analytics. Vercel may process technical request information to provide these measurements. Our private research and administration pages do not load Web Analytics. This is not a claim that hosting providers keep no logs.

We also count when visitors open a retailer's product listing or seller price from a HairProof product page. We store only daily totals by HairProof product and link type, without individual click records, cookies, persistent visitor identifiers, or destination URLs. Hosting services may still process standard technical request logs. The counts indicate links opened, not purchases.

Affiliate links

Some HairProof pages contain clearly labeled affiliate retailer links. HairProof may earn a commission when a shopper purchases through one. Editorial reporting, criticism, review inclusion and rankings are independent of those partnerships. When you follow an affiliate link, the affiliate network and retailer may process clicks and other information under their own privacy practices.

Hair stories and your private code

Approved hair stories may be visible to visitors. Stories waiting for review stay private. Your return code is like a password: anyone who has it may be able to update your story. Keep it safe.

Questions, corrections, and privacy requests

For questions, corrections to a source, or requests about your hair story, email hello@checkhairproof.com. Do not include your private return code. We may need further information to evaluate a request safely.

Shopper tools and usefulness feedback

We count product-page views, openings of original research sources, calculator use and comparison sharing by product. Source openings show that a link was selected, not that someone watched or agreed with a review. If you choose to answer whether a page helped, we record your answer and optional missing-information category. We do not ask for your name, email or a written message for this feedback, and we do not publish individual answers.

To limit repeat submissions, our server turns your network address into a daily keyed hash. We do not save the raw address in these measurement tables. Hashes expire from active use each day and are removed when new activity arrives after two days. Aggregate daily counts remain to help improve the site. People sharing a network may be counted together. Your browser may remember a feedback submission for 30 days to avoid asking again.

Product update emails

If you request product updates, we use your email address only to confirm your request and send new firsthand experiences for the products you choose. We use Resend to deliver these emails. We do not add you to promotional lists or use email tracking pixels.

You must confirm your email before updates begin. Each email includes an unsubscribe link. Unsubscribing removes your email address from that product's active subscription. Unconfirmed addresses are cleared after seven days. Private delivery records help prevent duplicate messages and stop emails after bounces or complaints. Confirmation and unsubscribe links are private, so please do not share them.
